TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 788,984, dated May 2,1905.

Application filed February 3. 1904. Serial No. 191,777-

To all whom it nuty concern:

Be it known that I, FRANK A. YOUNG, a citizen of the United States, anda resident of Syracuse, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Type-WritingMachines, of which the following is a specification.

My invention relates to improvements in the type-actions of type-writingmachines, especially those visible writing machines which are known asfront-strike machines, the general object of the invention being toprevent the type-bars from rebounding when they return to their normalpositions.

The invention consists of various features of construction,combinations, and arrange ments of parts, all to be hereinafter fullydescribed, and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference-numerals designatelike parts in the different views, Figure 1 is a side elevation of atype-action embodying the invention; Fig. 2, a side view, on an enlargedscale, of the typebar hanger and fragments of the type-bar andactuating-link; Fig. 8, a rear and end view of the hanger and type-bar,respectively, and a cross-section of the link on the plane a; w of Fig.2; and Fig. 4;, a side view of another hanger with fragments of atype-bar and actuating-link.

The invention is shown applied to a typeaction of a front-strike machinein which the type-bars are mounted on separately-detachable hangerssecured to a common segmental support. it will be understood, however,that hangers of various forms may be used or that the type-bar may bemounted on a hanger integral with the common type-bar segment or supportwithout materially affecting the invention.

The key-lever 1, having at its front end a finger-key 2, bears at itsrear end on a fulcrum 3 and is normally held by a spring 4:, attached toa cross-bar 5, against a fixed pad 6.

fulcrum 3, cross-bar 5, and pad 6 are secured The in the base of themachine-frame, which is like that of well-known front-striketype-writing machines. On the key-lever an upright sublever 7 is pivotedby a pin 8. This sublever, which extends below the key-lever, has nearits lower end a slot 9, by means of which the sublever engages with arod 10, which is attached at its ends to the sides of the frame.

The particular hanger represented in Figs. 1, 2, and 3 is a flat pieceof metal having the outline shown by full and dotted lines in thosefigures. The head 11 of the hanger forms with the stem 12 thereof areentrant right angle whose sides are the edge 13 of the head and therear edge 14 of the stem. The stem contains a recess 15, extending intoit from its front edge. The hanger-support 16, of which only across-section is shown, has substantially the form of the well-knownsegmental type-bar support of front-strike machines,

its upper face being a concave cylindrical surface whose axis passesthrough or near the printing-point on the platen. The front portion ofthis support or segment 16 contains a series of slots which extendthrough it from top to bottom, the faces of each slot being parallel toa plane which is one of a series of planes that contain and radiate fromthe axis of the upper surface of the segment. The stem 12 of the hangeris confined in one of these slots 17, in which it fits snugly, thehanger being fastened by a screw 18 in its proper position, with itsedges 13 and 14 in contact, respectively, with the upper face of thesegment and the back of the slot. The screw 18 fits in a threaded holein the front of the segment and is screwed tightly against the back ofthe recess 15 in the stem of the hanger. The head of the hanger isdirectly in front of the upper portion of the sublever 7.

The type-bar 19 covers the top and sides of the head of this hanger, asocket having fiat faces, between which the head of the hanger fits,being milled in the type-bar. The pivot 20 of the type-bar extendsthrough the walls of this socket and the head of the hanger, its endsbeing flush with the lateral faces of the type bar. The fiat edge or top21 of the socket, which covers the top of the head of the hanger whenthe type-bar is in its normal position, forms a catch 22 at the end ofthe type-bar, notches 23 being cut in the sides of the type-bar next tothis catch. On the typebar, close to the socket, is a lug 24, which isthinner than the socket. This lug may be formed by cutting away aportion of the typebar blank with a milling-tool. The swinging or typeend of the type-bar lies on a rest 25 when the parts of the type-actionare in their normal positions. This restis such as is usually attachedto arms extending forward from the type-bar segment. A restoring-spring26, connected with the type-bar, is secured at its front end to a hookor pin aflixed to the rest 25.

Between the sublever 7 and the type-bar is an actuating devicesuch, forexample, as the link 27. This link, which is pivoted at its rear end tothe upper end of the sublever 7 by a pin 28, extends forward from thesub lever to the lug 24 on the type-bar, the link being connected at itsfront end to the lug by a pin 29 passing through a slot 30 in the link.A hook or detent 31, formed on or affixed to this link, extends behindand under the catch 22 on the type-bar when the parts of the type-actionare in their normal positions, the rear end of the slot 30 in the linkthen being close to the pin 29. The link 27 may be a thin unfolded stripof metal, or it may be divided at its front end and extend on both sidesof the lug 24, each part having in it a slot 30 and being engagedthereby with the pin 29, and the hook 31 may be either thick enough toenter the notches 23 or thin enough to engage with the catch between thenotches only.

The type-bar secured behind the lost-m0- tion connection 29 30 to thelink 27 by the detent 31, engaged with the catch 22, is locked in itsnormal position. for the front end of the type-bar is then preventedfrom moving toward the platen 32 by the downward action of the rear endof the link 27 on the sublever 7 and the downward action of the catch 22on the detent 31 and on the link.

Other means besides the catch 22 and detent 31, operative on the linkbetween the pin 29 and the rear end of the link, may be used to preventthe part of the link next to the end of the type-bar from being raisedby the action of the type-bar on the link whether such means is alsooperative immediately on the type-bar or on the hanger or some otherpart of the machine.

The link may be locked to a hanger, as is shown, for example, by Fig. 4.The head 33 of the hanger of this figure forms a socket for thetype-bar, the stem 34 being like the stem 12 of the other hanger and therelation of the stem to the head being such that the hanger may beattached to the segment 16 by inserting the stem in a slot 17 andsecuring it therein, with a screw 18 pressing against the back of therecess 35 in the stem. On the head 33 of this hanger is a catch 36,formed by cutting in the head a notch 37 like the notches 22 in thetypebar 19. The typebar 38, which is pivoted by a pin 39 in the socketof this hanger, has on it a lug 40, to which an actuating-link 27 isconnected by a pin 29 passing through the slot 30 in the link. When thislink is pivoted at its rear end to a sublever 7 and the parts of thetype-action are in their normal positions, the hook or detent 31 on thelink extends behind and under the catch 36, and the type-bar is thenlocked.

When the finger-key 2 is depressed,.the upper end of the sublever 7 ismoved backward by the downward action of the pin 8 on the sublever andthe action of the upper edge of the slot 9 on the rod 10. The link 27 isdrawn backward by the sublever until the front end of the slot 30 is incontact with the pin 29, while the type-bar remains in its normalposition. During this part of the movement of the link the detent 31 iswithdrawn from the catch 22 or 36. The type-bar, which is then unlocked,as appears by Fig. 2, is thereafter actuated by the link acting on thepin 29 as it would on a common pivot. During the return of the type-barto its normal position under the action of the spring 26 the pin 29 isat the front end of the slot 30, and immediately after the movement ofthe type-bar is arrested by the rest 25 the detent 31 engages with thecatch 22 or 36, the link 27 continuing to move forward in consequence ofthe upward action of the spring 4 on the key-lever until the rear end ofthe slot 30 reaches the pin 29. By looking the type-bar as described atthe instant when it arrives at its normal position after each action itis prevented from rebounding into the path of any other type-bar.

The mechanism herein described and claimed, it will be seen, comprisesmeans whereby a type-bar is positively locked in its normal positionhowever rapid the movement of the type-bar may be when it strikes thetype-bar rest. The function of this locking mechanism therefore differsgreatly from that of devices which retard the movement of a type-bar asit approaches its normal position by means of friction produced by thesliding action of one device on another.

Type-actions like that described herein can be assembled and adjustedand removed from and replaced on the supporting-segment withoutdisturbing the relations between the counterparts of the lockingmechanism, and they afford in addition to the special advantages of thisinvention all the well-known advantages which are derived from othertype-actions provided with separately detachable type-bar hangers.

Certain features of the invention may be used without the others, andvarious changes may be made without departing from the spirit of theinvention.
